bad weather, or: to shoot or not to shoot

Hi everyone,

I've recently started playing SHIII again. With GWX2 and OLC off course.
And I must say, bad weather has now become a major pain in the ass. Wich, having been a fisherman on the Norht Atlantic know from experience, it realy is in real life. My question for you guys is: if you spot a target in horrible weather conditions, do you attack, or save your fish?

The reason I ask is I'm natuaraly inclined to attack and shoot at everything that happens to wonder in front of my scope. But, in bad weather targeting becomes a lot harder and I seem to waste a lot of torpedos. (I don't have any problems in good weather conditions though, and regulary hit targets.)

So: to shoot or not to shoot? That is the question!

P.s., anybody know what they used to do in real life?
